System Error Logging
The AAM's system error log will record error logs locally. These logs may be viewed again
after a warm restart.

Alarm LED

An ALM (alarm) LED lights when the AAM is overheated or the voltage readings are outside
the tolerance levels.

Bandwidth Control

The AAM supports rate limiting in 64Kbps increments allowing you to create different service
plans.

Quality of Service

The AAM has four priority queues so you can ensure mission-critical data gets delivered on
time.
Follows the IEEE 802.1p priority setting standard.

Flow Control

The AAM uses IEEE 802.3 flow control to manage the sending of traffic so the sending device
does not transmit more than the receiving device can process. This helps prevent traffic from
being dropped and having to be resent.

1.3 Applications

These are the main applications for the AAM:
• Internet access and multimedia services for Multiple Tenant Units (MTU).
• Other applications include telemedicine, surveillance systems, remote servers systems,
cellular base stations and high-quality teleconferencing.

1.3.1 MTU Application

The following diagram depicts a typical application of the AAM with ADSL modems, in a
large residential building, or multiple tenant unit (MTU), that leverages existing phone line
wiring to provide Internet access to all tenants. ADSL service can coexist with voice service
on the same line.
